Arnautovic is a very good player on his day a bit like Sess the key part of that statement is the qualifying "on his day" but how frequently is his day? A £100k a week would imply quite frequently. The question for Stoke and by extension ourselves because we are a similar sized club is should you pay it and if you don't will somebody else?
Firstly mid-table premier league clubs are edging slowly towards the £100,000 a week footballer if reports were true about the £70,000 a week we were prepared to pay Ba then a £100,000 isn't that far fetched. The TV deal will propel the top earners at teams like Stoke close to that figure, Aranutovic knows this and is just laying down a marker.
Secondly will other clubs pay Aranutovic what he wants? The clubs that habitually pay £100,000 a week even to players who are not among their best and brightest are few and far between and none that aren't champions league regulars outside England.
I think Stoke could and should call his agent's bluff on this because there is simply nobody else who will stump up that sort of money particularly with a big fee involved. All that said football has a habit of astounding me when it comes to these matters.
